UZ Pyxidis

UZ Pyxidis is a semiregular variable star in the constellation Pyxis. It is located about 2100 light-years (650 parsecs) away from the Earth. Its apparent magnitude is about 9.0, which is dim enough that it cannot be seen with the unaided eye.

UZ Pyxidis is a carbon star. These types of stars are known for having large amounts of carbon in their atmospheres, forming carbon compounds that make the star appear strikingly red. Under the Morgan–Keenan classification of carbon stars, UZ Pyxidis' spectral type is C5₅; if it were a normal giant star, this would correspond to a spectral type of about K5. It is also unusual in that it has very strong isotopic bands of C₂ and CN.
